Structural Design and Construction Challenges on the South and West of Edmonton Area Development Project
Bibliographic record
Abstract
In 2013, AltaLink initiated work on the South and West of Edmonton Area development project comprised of multiple 138-kV and 240-kV circuit modifications. Scopes included greenfield construction, rebuilding existing lines, and tapping existing lines to new substations. The complicated project scopes were challenging to construct due to outage constraints, environmental restrictions, and the need for multiple foundation solutions. Proper outage planning with the AltaLink Control Center was imperative and directly impacted the construction sequencing of the project. Environmental concerns affected the project in multiple ways: work restrictions during bird nesting and migration seasons, requirements for rig matting in environmentally sensitive and wet areas, and the use of vehicle wash stations. A variety of structure types were implemented on the project including double-circuit latticed steel towers, single-, double-, and triple-circuit tubular steel poles, and wood poles. Foundation types, including drilled shafts, helical foundations, and direct embed foundations, were selected based on structure type and location. Construction commenced in early 2017, and the project was placed in service in December 2017.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
